Diving mask

ABSTRACT

A diving mask includes primarily at least one draining guide protruded outward which is located at a proper position of pressure equalizers protruded inward in a nosepiece of the diving mask. The draining guide is connected to a mirror and nasal wings of the nosepiece, which forms the pressure equalizers with draining guides. In addition to facilitate to use fingers to pinch nostrils to balance ear pressure with the pressure equalizers, when water permeates into the mirror, the water in the mirror can be smoothly drained into a bottom of the nosepiece through the draining guides. Therefore, a diver can lift up the bottom of diving mask under the water and then blow hard with a nose to completely expel out the water.

BACKGROUND OF THE INVENTION

a) Field of the Invention

The present invention relates to a diving mask, and more particularly toa diving mask wherein at least one draining guide protruded outward islocated at a proper position of a bottom of pressure equalizersprotruded inward in a nosepiece of the diving mask. In addition toequalize ear pressure, the pressure equalizers of the draining guidescan also drain the permeated water in the mirror into a bottom of thenosepiece to completely expel out the permeated water, thereby avoidingthe water to be remained in the mirror of mask, and causing aninsufficient vision to the diver.

b) Description of the Prior Art

Referring to FIG. 1, a conventional diving mask 100 is composed of aframe 101, a mask 102, and a mirror 103, wherein a ring of skirt 1021 issurrounding a periphery of the silicon mask 102 to fit over a face of adiver, and a nosepiece 1022 is protruded out from a center to cover on anose of the diver. Pressure equalizers 1023 protruded inward are locatedat two sides of the nosepiece 1022 respectively. The pressure equalizers1023 are located at nasal wings of the diver, so that the diver can putfingers into outsides of the pressure equalizers 1023 and pinch thenostrils for equalizing ear pressure under water. However, due tofactors such as water pressure and a facial shape of a wearer, etc, seawater will usually permeate into the mask 100 and mostly stay in thenosepiece 1022 and a bottom of the mirror 103. Therefore, to expel outthe permeated water in the mask 100, the diver must lift up the bottomof mask 100 to leave a gap, and to blow hard with the nose to expel thepermeated water. In a practical operation, the permeated water in thenosepiece 1022 of the mask 100 is easier to be expelled, whereas thepermeated water at the bottom of the mirror 103 cannot smoothly flowinto the nosepiece 1022 by a separation of the pressure equalizers 1023protruded inward, thereby not easily to be expelled. As the sea waterwhich remains in the mirror 103 will affect a vision of the diver, ithas always been troubling the diver.

SUMMARY OF THE INVENTION

The primary object of the present invention is to install at least onedraining guide protruded outward at a proper position of a bottom ofpressure equalizers protruded inward in a nosepiece of the diving mask,wherein in addition to equalize ear pressure, the pressure equalizers ofthe draining guides can also smoothly drain the permeated water in themirror into a bottom of the nosepiece to completely expel out the seawater permeated into the diving mask, thereby avoiding the water to beremained in the mirror of mask, and causing a trouble to the diver.

To enable a further understanding of the said objectives and thetechnological methods of the invention herein, the brief description ofthe drawings below is followed by the detailed description of thepreferred embodiments.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to FIG. 2, a diving mask 1 of the present invention comprisesprimarily a frame 10 made of a hard material, a mask 20 made of a softmaterial, and a mirror 30, wherein a ring of skirt 201 is surrounding aperiphery of the silicon mask 20 to fit over a face of a diver, and twopressure equalizers 203 protruded inward are located at two sides of anosepiece 202 which is protruded outward in a center. The diver can putfingers into outsides of the pressure equalizers 203 and pinch thenostrils to equalize ear pressure under water.

At least one draining guide 2031 which is protruded outward is locatedat a proper position of the pressure equalizers 203 protruded inward inthe nosepiece 202 of the mask 20, and is connected to the mirror 30 andnasal wings of the nosepiece 202. When water permeates into the divingmask 1, the draining guide 2031 can smoothly drain the water in themirror 30 into a bottom of the nosepiece 202, such that the diver canlift up the bottom of diving mask 1 under the water and blow with thenose to completely expel out the permeated water, thereby accuratelysolving a problem which always troubles the diver during a process ofoperation.

Referring to FIG. 2, FIG. 3 and FIG. 4, a one-way draining device 2 islocated on a hole 2021 at a bottom of the nosepiece 202 of the mask 20.The draining device 2 is composed of an inner seat 21, a valve sheet 22,an outer seat 23, and a cap 24, wherein a seat hole 211 which is in asame shape with the hole 2021 of the nosepiece 202 is located at acenter of the inner seat 21, a ring of U-shape latch groove 212 issurrounding a periphery of the seat hole 211, and a latch hole 213 islocated at one end of the seat hole 211. Accordingly, the inner seat 21is latched on the hole 2021 of the nosepiece 202 with the latch groove212 from an inner side to an outer side. A latch pin 221 is located at acenter of the soft valve sheet 22, and can be extended into a latch hole233 in a center of the outer seat 23 for positioning. The valve sheet 22can cover a seat hole 231 of the outer seat 23, which forms a one-wayvalve that can expel water in one side, from an inner side to an outerside. A transversal latch bar 232 is located at an inner rim of the seathole 231 of the outer seat 23, such that the outer seat 23 can belatched into the latch groove 212 of inner seat 21 with the latch bar232. A positioning pin 234 is located at one end of the triangular outerseat 23, and two hook grooves 235 are located the other two ends,respectively. A draining hole 241 is located on the triangular cap 24which is in the same shape as the outer seat 23. A pin hole 242 islocated at one end of the cap 24 having a U-shape opening, and two hooks243 are located at the other two ends, respectively. When the cap 24slides on the aforementioned outer seat 23, the two hooks 243 of the cap24 are respectively hooked into the hook grooves 235 of the outer seat23 for positioning, and the pin hole 242 of the cap 24 is used toprovide for an insertion of the positioning pin 234 of the outer seat23. Accordingly, the one-way draining device 2 of the present inventionis assembled, such that the exterior seat water cannot enter into thediving mask 1 from an outside of the valve sheet 22, and a user can blowto smoothly expel out the water from the one-way valve sheet 22 when thesea water permeates into the diving mask 1.

Accordingly, at least one draining guide protruded outward which islocated at a proper position of the pressure equalizers protruded inwardin the nosepiece of the diving mask is used in the present invention. Inaddition to equalize ear pressure with the pressure equalizers, whenwater permeates into the diving mask of a diver, the draining guide candrain the permeated water in the mirror into the bottom of nosepiece, tofacilitate a complete expelling, thereby avoiding the water remained inthe mirror to cause a trouble to the diver.
